ABSTRACT The Construction industry in very much in need of cost efficient and well performing materials acting as substituent to traditional ones. Although natural river sand outperforms all other resources in the production of concrete, its supply is depleting owing to deliberate overexploitation around the world. This project looks into the possibility of using readily available, inorganic, and inert CSKFB waste material to efficiently replace naturally available river sand in the production of good and lasting concretes. Based on its initial physico-chemical resemblance to sand, the Spent kiln fire bricks (i.e., a SW material primarily manufactured in foundries and directly dumped as waste material to MSW) is considered as an alternative material for partially substituting sand in the construction of excellent concrete. As a result, in this study, a combination of "effective waste management" and "resource conservation" was used. Keywords: Fine aggregates, Crushed Spent Kiln Fire Bricks, Refractory Bricks, Rapid Chloride Permeation Test.
1. INTRODUCTION 1.1 GENERAL Concrete is an extensively used construction material, with applications in structural, geotechnical, environmental, transportation, and highway engineering. This is due to its robust and lasting properties, as well as the fact that it can be molded into a variety of forms and sizes, from basic prisms to curved domes and shells. Aggregates serve a crucial function in the concrete matrix, reducing shrinkage and improving durability. Crushed rock, gravel, and river sand are examples of natural aggregates that may be used in the construction of concrete. Because of its angularity, hardness, and toughness, sand collected from natural stream deposits is ideal for use as FA in concrete manufacturing .Overharvesting of geomaterials in recent decades has resulted in resource depletion, environmental deterioration, and high energy use. As a result, the partial or complete replacement of of fine aggregates by the other compatible materials like sintered fly ash, crushed rock dust, quarry dust, glass powder, recycled concrete dust, and others are being studied over the past 2 decades from the standpoint of ecological protection.
1.2 INVESTIGATION OBJECTIVES The primary goal of this study is to determine whether locally and freely available SKFB may be used to partially replace natural sand in the manufacturing of good concrete through acquisition of necessary items for trial concretes, including SKFB, and elemental studies to determine appropriate physico-chemical characteristics. Adoption of simplified mix design procedure as per IS: 10262-1982 as design mix to arrive at various M25 concretes leading to the preparation of FB10, FB20, FB30, FB40, FB50, and FB60 as mix proportions according to the respective percentage of effective fine aggregate replacement for efficiency. Fabrication, curing, and testing of several cube, cylindrical of both conventional as well as CSKFB concrete specimens for the various testing aspects took place. Such as:
